Recent studies indicated that the toxicity of heavy metal ions caused a series of environmental, food, and human health problems. Chemical ionochromic sensors are crucial for detecting these toxicity ions. Incorporating organic ligands into π-conjugated polymers made them receptors for metal ions, resulting in an ionochromism phenomenon, which is promising to develop chemosensors for metal ions. This review highlights the recent advances in π-conjugated polymers with ionochromism to metal ions, which may guide rational structural design and evaluation of chemosensors.

金属配体诱导的π共轭材料的电致变色

最近的研究表明，重金属离子的毒性引起了一系列环境，食物和人类健康问题。化学离子变色传感器对于检测这些毒性离子至关重要。将有机配体掺入π-共轭聚合物中使它们成为金属离子的受体，导致电致变色现象，这有望开发出用于金属离子的化学传感器。这篇综述突出了具有金属离子电致变色作用的π-共轭聚合物的最新进展，这可能指导化学传感器的合理结构设计和评估。
